I am quite pleased with this power supply control board except for one problem. The circuit is designed to use (3) TL081 Op Amps which have an Offset circuit built in. The Offset is necessary in the U2 position (lower right hand corner above the blue trimmer) if you want to bring your voltage to zero volts when the voltage control is all the way down. Unfortunately the TL081 chips that are currently being supplied with the kit are not quality and they do not have the Offset circuitry built into the chip. If you want to be able to zero your voltage output when the voltage control is all the way down you will have to purchase a quality TL081 chip for this position. At the price they are selling these kits for this is a small problem and easily remedied.
